MULTIPLE CASH-REGISTER.

Specification of Letters Patent.

Patented Nov. 14, 1.911.

Application filed March 3, 1910. Serial No. 546,981.

To all whom it may concern:

Be it known that I, EDWARD J Von PEIN, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Multiple Cash- Registers, of which I declare the following to be a full, clear, and exact description.

This invention relates to cost and selling price cash registers; that is, cash registers which are provided with means for recording in separate totalizers the cost and selling price of articles.

The improvements of the present invention are shown in the drawings applied to the type of cash register described in the patent to Carroll, #708,639, granted July 1, 1902, certain improvements which are shown in pending applications of Edward Von Pein, Serial Nos. 342,887 and 415,959, filed on November 10, 1906 and February 1 1, 1908 respectively. Only such parts of the register as relate directly to the present invention are shown in the annexed drawings. The class of register referred to is provided with a rotatable reel which carries a plurality of totalizers, with means for rotating this reel to bring any desired totalizer into operative relation with the actuating mechanism. In the present invention one of these totalizers is used for receiving the cost records. The totalizer reel is rotated by means of a lever and when this lever is in the position at which the cost totalizer is in operative relation with the actuating mechanism the indicator flashes will cover the indicators during and after the operation of the machine, under the control of the totalizer setting lever. v

The object of causing the indicators to remain hidden during cost registrations is to prevent the indication to customers of cost prices.

A further object is to improve the indica tion on this type of machine. Roller indicators bearing abbreviations of transactions have been provided heretofore, but the present invention adds tothis a second roller indicator bearing full word indicia as more fully described herein.

With these and incidental objects in view the invention consists in certain novel fea tures of construction and combinations of parts the essential elements of which are set forth in appended claims and the prof erred form of embodiment of which is hereinafter described with reference to the drawings which accompany and form part of the specification.

Of said drawings: Figure 1 is a frag-- mentary front elevation of a cash register constructed according to the invention. Fig. 2 is a left side elevation of the same- Fig. 3 is a left side elevation with the mr ltiple totalizer reel omitted. Fig. 1 is a transverse vertical section of the register taken n the line 4.l of Fig. 1. Fig. 5 is a transverse vertical section taken on the line 55 of lig. 1. F ig. 6 is a transverse vertical section taken on the line 6--6 of Fig. 1. Figs. 7 ind 8 are details in side elevation and partly in section of the flash operating mechanism.

onthe line 9-9 of Fig. 1. Fig. 1(* is a transverse vertical section of a register and illustrates a modification of the invention. Fig. 11 is a horizontal section taken on the line 11-11 of Fig. 10 and illustrates both the main invention and the modification.

In the drawings the lever by means of which the totalizer reel is rotated is indicated by numeral 1. The lever is p: voted on a shaft 2 and is rigidly connected with a segment gear 3. The segment gear 3 meshes with an intermediate gear 4: which in turn meshes with a pinion 5 fast on an indicator drum 6; therefore the movement of the lever 1 is communicated to the indicator which is provided with two sets of indicia for indicating different P0811111 )IIS of the lever 1. One of these sets of indLcia is readable at the rear of the machine and the other is readable at the front of the machine, the machine cabinet being provided with suitable sight openings for the pn rpose.

The lever 1 is integral with a segment gear 7 meshing with a segment gear 8 which is fixed to a shaft 9. This shaft also (arries a segment gear which meshes with a pinion concentric and rigid with the totalizer reel 10 which is pivoted to the frame of tle machine at 11. The specific construction of the totalizer reel is not illustrated in the drawings as it may be found in the patent and applications above referred to. The rotation of the reel upon the settin lever 1 causes some particular totalizer, de pending upon the extent of movement of Fig. 9 is a transverse vertical section taken )f the I the lever 1, to be brought opposite to segment gears which are carried by sleeves 12, Figs. 3 and 4. These segment gears are not shown in the drawings but the sleeves 12 are rigidly connected to intermediate gears 13 (Fig. 6) which receive differential rotation from segment gears 14 controlled by the value keys of the register.

The reel 10 is mounted on a slide 15 (Fig. 2) which is set in the ways 16, and is provided with a pin 18 extending through an L shaped slot 19 in an arm 20 which is pivoted on a pin 21 and is provided with a roller 22 extending into the race 23 of a cam which is carried by a drive shaft 25. The drive shaft 25 is caused to make one rotation upon each operation of the machine in the direction indicated by the arrow 26, and as the roller 22 normally extends into the race 23 of the cam the arm 20 will be oscillated upon each operation of the machine. The arm is first moved downward engaging the pin 18 at the part 27 of the slot 19 thereby camming the slide 15 upwardly and bringing the particular totalizer which is opposite the actuating segment gears into mesh therewith. The totalizer is held in mesh during the time the roller 22 is in the circular part 28 of the cam race, at which time the totalizer is actuated. After the totalizer is actuated the arm 20 is returned to its normal position thus causing the totalizer to be unmeshed from the actuating segments.

The-lever 1 is alined in any of its set positions'by a'spring pressed plunger 29 which co-acts for this purpose with an alining plate 30. A thumb grip .31 on the lever 1 is pressed toward the lever 1 in order to move the plunger 29 away from the alining plate, and'controls the operation of a looking arm 32 for the purpose of preventing the operation of the driving mechanism of the machine while the lever 1 is being shifted, at which time a nose 33 on an arm 32 is in a notch 34 of a disk 35 which is carried by the main drive shaft 25. The locking lever 32 is normally held out of engagement with the disk 35 by a spring 36 but when the thumb grip 31 is moved toward the lever 1 an arm 37 of the grip engages a member 38 which carries the plunger 29 and is itself carried by parallel arms pivoted on pins 39 and 40 to lever 1. The plunger 29 has a shoulder 41 which extends across the front edge of a plate 42 which is carried by a pair of arms 43 and 44 which are respectively pivoted on a shaft 45 and a pin 46. The arm 43 is fixed to the shaft 45 which carries the arm 32. Because of this arrangement when the plunger 29 is moved rearwardly the arm 43 rocks rearwardly andcauses the arm 32 to move upwardly' bringing the nose 33 of the arm into the notch 34 thus preventing rotation of the drive shaft 25 when the plunger 29 is out of engagement with the alining plate 30.

Indicator s0ree'ns.The indicator screens 50, 51, 52 and 53 are shown in Fig. 8 in their normal positions, in which positions they do not cover the indicator sight openings in the register cabinet. The screens are ordinarily left in this position at the completion of each operation of the machine. The screens and 51 are carried by arms 54 loosely pivoted upon the indicator shaft 56. One of the arms 54 carries a segment gear 57 preferably made integral therewith and having a pin 58 which co-acts with a hook shaped pawl 59 carried by a lever 60 for the purpose of connecting the segment gear 57 to the lever 60 which is also loosely pivoted upon the shaft 56 and connected by a pitman 61 to a cam 62 (Fig. 6) which is carried by main drive shaft 25. The cam 62 causes a reciprocation of the pitman 61 upon each operation of the machine. The pitman is first drawn downwardly causing the pawl 59 to be rocked upwardly to the position in which it is shown in Fig. 7. But before the drive shaft is rotated the lever 1 is first operated by pressing the thumb grip 31 toward the lever. This causes the arm 32 (Fig. 3) to be rocked upwardly as previously described. The arm 32 (Fig. 5) is provided with a pin 63 which extends through a slot 64 in a lever 65 which is pivoted to the frame of the machine on a pin 66 and at its upper end is provided with a lug 68 which extends at right angles to the lever across the tail 69 (Fig. 8) of the pawl 59. The pawl 59 is normally urged into engagement with the pin 58 by a spring 70, but when the grip 31 of the lever 1 is operated the arm 32 in rocking upwardly will cause the upper end of the lever 65 to rock forwardly so that the lug 68 of the lever engages the tail of the pawl 59 and rocks the pawl out of engagement wit hthe pin 58. The spring 63 then quickly rocks the indicator screen carrying arms 54 and 55 into 'such position that the screens will cover the indicator sight openings of the cabinet. The pitman 61 is held in its lower position during the greater part of the rotation of the shaft 25 but asthe shaft 25 nears its home position the pitman is again raised by the cam 62 causing pawl 59 to return to its original position as indicated in Fig. 8. When the pawl 59 reaches its upper position it ordinarily rocks forwardly as it passes the pin 58 thus connecting segment 57 with the lever 60. Therefore upon the return of the pawl 59 to its original position the segment 57 will also be returned to its initial position causing the indicator screens to rock away from the sight openings and therefore expose the setting of the indicators. The indicators are set while the roller 71 is in the circulator part 72 of the 40 a tive relationwith the actuating mechanism as in race of the cam 62 and it is at this time that the screens are held in their moved positions.

One of the objects of the present inven tion is to cause the screens 50 and 51 to be held in'the position in which they cover the indication of a registration whenever a cost registration is made, and to this end means pitman 61. the screens 50 and 51 will be left at the completion of the operation of the machine in the posit-ion to which they are drawn by the spring 63. For the purpose of rockin thepawl out of engaging position with t e pin 58 .the pawl is provided with .a pin 73 for co-acting with an arm 74 which .is carriedby a short shaft 75. 75 carries an arm 76 (Fig. 4.) which isa duplication of the arm 74 but co-acts with a pin 77 carried in any one of nine holes7 8 in the pinion 5 of the indicator 6. It was previously stated" that the indicator 6 serves the purpose of indicating which totalizer of the reel 10 is in operative relation with the actuating mechanism and as this depends upon the setting of the lever 1 it also indicates the position of the lever 1. There are nine totalizers mounted upon the reel 10 and the hole 78" which is opposite the surface 7 9 of the arm 76 corresponds with the totalizer which is in an operative position. The pin 77 is inserted in the particular hole 78 which corres ends to the totalizer it is desired to use on receiving cost registrations. When the cost totalizer is in operathe pin 77 is in engagement with the arm 76 thus holdin the arm .7 6 in the position in which it is s own by full lines in Fig. 4. The angular position of the arm 74 on the shaft 75 coincides with the position of the arm 76; therefore-when the arm 76 is in the position in which it is shown in Fig. 4 the arm 74 will be in the position in which it is shown by full lines in Fig. 7. When in this position it is in the path of movement of'the pin 73 of the pawl 59 and when the pawl is carried upward the pin 73' engages the surface-80 of the arm Mi-causing the pawl to be cammed to the angular position shown by full lines in Fig. 7 with respect to its pivot by the timexthe pawl reaches its u ward position. This 0 eration is illustrate by Fig. 7 and with t e pawl in the position in whichit is shown by full lines the position of theflashes 50 and 51 will not be disturbed-when the pawl is returned to its original-position upon thereturn of the pitman 61.

An indicator for classes of transactions is The shaft to the transaction indicator 91.

provided, and this is covered at proper times by the screens 52 and53 before referred to.

These screens may move with screens 51' and 52 and mechanism is therefore employed connecting the two sets of screens so as to move screens 52 and 53 with screens 50 and 51. To this end the'segment gear57 meshes with a gear 81 which is. rigidly mounted upon a, shaft 82 also carrying a ear 84 meshing with a segment. gear 85 ig. 5) which is loosely journaled upon the st aft 56 and is provided with a rearwardly ex-' tending arm 86 to which is pivoted by a pin 87 a link 89 connecting the arm 86 with me of'the carrying arms 90 of the screens 52 and 53. When the segment gear 57 Inc veS' up from the position in which it vis shown in Fig. 8 to the position in which it is shc wn in Fig. 7 it rocks the screens 50 and 51 into position for covering the indicators and through the gears 81 and 84 causes asi iiilar upward movement of the segment gear 85 which by pulling the link 89 downwardly brings the-screens 52, and 53 to the posit ion rearwardly extending arm 86 of the reg" ment gear 85 (Fig. 5) also carries an a in: ing arm 92 providedwith a lug 93 which when the screens 52 and 53 return to t-leir normal position engages one of the edgeg of a squared disk 94 carried b a shaft 95 supporting the transaction in 'icator. The engagement between the fiat surface of the lug 93 and one of the edges of the disk94causes the transaction indicator to be =alined locked in its set position. q

Transaction indicator setting mes/Lam's The manner in which the transaction indie cator is set is as follows: This indicator is for the purpose ofindicating the four p1 incipal classes of transactions; it is provided with two sets of indications-onefor re ading. at the'front of the machine and one for reading at the rear of the machine. Tl .ese

indications read Paid out Charge, Received on account and Cash. The

indicator 6 is rigid with a disk .96 (Figs. 1

and 3) which is provided with a spiral lace 97 in which extends a roller 98 on a segm ent gear 99 which meshes with a pinion 100 :Fast If the hand lever 1 is moved upward the tisk 96 will rotate in the direction indicated by and the arrow 102 (Fig. 3) and if the lever l is nism when the lever 1 is in its lowest p )sition s the one upon which paldwO'lt transactions are recorded; therefore wien is the charge the roller 98 is engaged at the part 103 of thecam race 97' the words Paid out will be indicated by the indicator 91. Assuming that the next higher position of the lever 1 position the first unit of movement of the lever 1 will cause the disk 96 to rotate enough to cause the segment gear to rock far enough to rotate the transaction indicator through one-fourth of a rotation. The indicator thereby brings the word Charge before the sight openings in the register. The third position of the indicator is the received on account position, therefore the third position of the lever is the received on account position for the lever. The fourth position of the indicator is the cash position; therefore the fourth position of the lever 1 is also a cash position for the lever. The 5th, 6th, 7th and 8th positions of the lever 1 may all be cash positions. The indicator 91 of course does not need corres nding positions for all these cash ositions of the lever 1. For this reason rom the 4th to the 7th unit of movement of the cam 96 the race of the cam is circular thus not altering the setting of the indicator 91 as the cam 96 passes through these units of movement. The final or 8th unit of movement of the cam 96 also does not affect the position of the segment gear 99. The 8th unit of movement of the cam 96 corresponds to the movement of the lever 1 from its 8th to its 9th settings. The highest position of the lever 1 may be its position when the cost totalizer is in operative relation with the actuating mechanism and as the screens remain over the indicators when a cost registration is made it is not necessary to provide means for indicating the word Cost; therefore the indicator is left at its Cash reading.

A main or grand totalizer is represented at 105, Fig. 9. This totalizer is actuated each time one of the cash totalizers or 9 received on account totalizer of the reel is actuated and to a like extent. The totalizer 105 therefore receives all the amountswhich are added to these two difierent kinds of totalizers ofthe reel. The totalizer 105 and the means for actuating the same are fully described in the before mentioned patents, but it may be mentioned that it receives rotation from the segment gears 14 which are controlled in their movement by the value keys. As this totalizer is actuated only when either a cash or received on account transaction is recorded it is necessary to provide means for preventing engagement of the totalizer 105 with its actuating mechanism whenever a cost, charge or paid out registration is made. The pinions which comprise the totalizer 105 are loosely journaled upon a shaft 106 and at the side of each pinion ofreturning the gears 13 and the pinions on the shaft 106 to their zero positions. The segments 14 then rise extents which are determined by the depressed keys causing the gears 13 and the pinions with which they mesh to rotate similar extents away from their zero positions. When the segment gears 14 are at rest in their zero positions broad pinions 107 are rocked into mesh with the pinions on the shaft 106 thus connecting the totalizer pinions in pairs with the pinions which mesh with the gears 13. By this means the totalizer is forwardly rotated as desired. The totalizer pinions 107 are carried by arms 108 which are fixed to a shaft 109 (Fig. 9). The shaft 109 carries a downwardly extending arm 110 which is normally drawn by a spring 111 into such position that the broad pinions 107 will be outof mesh with the pinions on the shaft 106. The arm 110 carries a pin 112 upon which rests the hook like end 113 of a pitman 114, which is reciprocated at the proper time for meshing and unmeshing the broad pinions 107 by a cam 115 carried by the main drive shaft 25.

In order to disconnect the main totalizer from the differential mechanism it is merely necessary to disconnect the pitman 114 from the arm 110 thus permitting the spring 111 to hold the broad pinions 107 out of mesh during the entire operation of the machine. The lifting of the pitman 114 out of engagement with the pin 112 is determined by the setting'of the reel lever 1. The setting of the lever 1 (Fig. 3) is communicated to a slide shaft 116 by the segment gear 7, the segment gear 8, the shaft 9, a bevel gear 117 (Fig. 11) on the shaft 9, a bevel gear 118, and a segment gear 119 which is rigid with the bevel gear 118. The segment gear 119 meshes with a rack 120 which is carried by shaft 116. Because of the connections between the lever 1 and the shaft 116 the shaft 116 will be moved in a longitudinal direction in exact correspondence with the angular movement of the lever 1 upon the setting of the lever. The shaft 116 may also be oscillated upon its axis and the teeth of the rack 120 are curved so as not to prevent the oscillation of the shaft and also for the purpose of not becoming unmeshed from the segment gear 119 upon such oscillation. The shaft 116 (Fig. 9) is oscillated to invariable extents upon operations of the machine by its connections-arm 121, link 122 and arm 123 with the shaft 124. The shaft 124 is also oscillated to invariable extents by a crank and pitman connection with the drive shaft 25, as described in the before mentioned patents. An arm 125 is rigidly carried by the shaft 116 and therefore moves with the shaft when the shaft is moved in a longitudinal direction and is also oscillated when the shaft is oscillated. The longitudinal movement of the shaft 116 may or may not bring the arn1125 below one of a series of pins 126, depending upon the positioning of the lever 1. An arm 127 (Figs. 9 and 11) which carries the pins 126 is provided with a plurality of seats 128 for these pins and the location of these seating holes with respect to the sidewise movement of the arm 125 corresponds to the settings of the lever 1. For instance, when the lever 1 is set in its lowest position the arm 125 will be brought opposite the hole at the right of the plate 127. If there is a pin in this particular hole then when the shaft 116 is rocked on its axis the arm 125 will engage the pin and. thereby rock an arm 129 which carries the plate 127 causing a link 130 to be pushed upwardly. The link130 (Fig. 9) is pivoted to the arm 129 at 131 and. to pitman 114 at 132. The upward movement of the link 130 causes the pitman to be rocked upwardly away from the pin 112 and this movement of the link occurs before the part 133 of the race of the cam 115 engages the roller 134 of the pitman. Therefore when the pitman is pro jected outwardly it will not cause the broad pinions 107 to be rocked into mesh with the pinions on shaft 106, and thus the rotation of-the intermediate gears 13 (Fig. 6) will not be communicated to the main -totalizer '105.

It is usually desired to have the main totalizer accumulate amounts which are received, and it is therefore necessary to have the main totalizer out of operative relation with the differential mechanism when paid out, charge or cost registrations'are made. For this reason pins are placed in such of the holes 128 as corresponds to the "aid out charge and cost totalizers of the reel. The arrangement of the throwout mechanism for the main totalizer permits the selection of different positions of lever 1 for representing different classes of transactions. However, it is desirable that the cost and cash totalizers be grouped in such positions that the circular part of the race 97 (Fig. 3) in the cam 96 will be in engagement with the roller 98 when the lever 1 is in the correct position for these totalizers because the special indicator 91 will remain in the Cash reading when the roller 98 is in the circular part of-thc race.

A mwclz'ficaton.1n the foregoing de-- scription the reel totalizers are mentioned as employed for recording different classes of transactions but it may be desirableto use the reel totalizers as clerks totalizers. If suchis the case a bank of transaction keys as illustrated in Fig. is provided. The keys 135, 136, 137, 138 and 139 respectively represent the paid out, charge, cost received on account and cash keys. The paid out, charge and cost keys control means for preventing the operatiol. of the main totalizer when one of these keys is depressed upon a registration. Each of these keys carries a pin 140 which when 2 key is depressed engages a lever 141 rocking the same rearwardly. The lever 141 is connected by a link 142 to an arm 143 one shaft 144. This shaft carries an arm 145 (Figs. 9 and 11) which when the shaft is rocked upon the depression of one of these three keys, engages the arm 129 rocking the arm upwardly and thereby permitting the broad pinions 107 to remain out of mesh upon the operation of the machine. In this modification special totalizers are not provided. special transactions being recorded by the printing mechanism alone. The same construction of the indicator screens is however provided. But in place of having pin 77 (Fig. 4) in the gear 5 the pin is placed in a gear 146 (Fig. 8), which gear is provided with holes 147 for receiving the pin and meshes with an intermediate gear 148 which is controlled by the bank of special keys. The rocking of the lever 74 will then depend upon the position of the pin and the extent of the rotation of gear 146 as con trolled by the bank of special keys. As previously described, when the arm 74 is rocked outwardly it causes the pawl 59 to be rocked away from co-acting relation with the pin 58 and for this reason upon the operation of the machine the screens will be left in' their covering position.

CZerlcs initial bank.-The clerks initial indicator 6 may indicate the class of article sold as the machine is provided with five cash totalizers and the indicator drum rotates when the lever 1 is moved to cause the reel to rotate from. the position in which one of these totalizers is in operative rela tion with the actuating mechanism to the osition in which another of these totalizers is in operative relation with the actuating mechanism while the indicator 91: remains at the cash position.

Operatz'0n.-In recounting the operation of the device a cost and a selling price entry will be described in order. To enter a cost price the lever 1 (Fig. 3) is adjusted to the redetermined cost position. To adjust the ever 1, thumb grip 31 is pressed toward lever 1, by its lug 37 forcing bolt 29 out of one of notches in plate 30 and the lever 1 is rocked to the desired position. Rearward movement of bolt 29 through its shoulder 41 forces plate 42 rearward, thus rocking locking arm 32 temporarily into locking position with disk 35 on the main drive shaft 25. This movement of locking arm 32 rocks lever 65 (Fig. 4:) around its pivot 66 engaging lug 68 .with the tail of pawl 59 thus releasing both pairs of indicator screens and permitting springs 63 (Fig. 8) to rock the screens to concealing positlon. Pawl 59 being normally in the position in which it is shown in Fig. 8 and spring pressed into engagement with pin 58, its operation when engaged by lug 68 is simply to rock out of engagement permitting screens 50 and 51 to move to concealing position. Segment gear 57 on the screen carrying arm, by rotating shaft 82, communicates the motion to screens 52 and 53 (Fig. 5), which then cover the transaction indicator 91. The adjustment of lever 1, by its toothed segment 7, segment gear 8, shaft 9 and segment gear thereon (not shown) rotates reel 10 (Fig. 2) the required distance to position the desired totalizer below actuating segments (not shown) on sleeves 12. Also adjustment of the lever 1 shifts shaft 116 (Fig. 11) in the direction of its length so that arm 125 carried thereby will be positioned below one of pins 126 thereby making the main totalizer throwout mechanism effective. When the lever 1 is properly adjusted and thumb grip 31 released, arm 32 returns to normal unlocking position. The amount keys representing the cost price and a clerks initial key are depressed and then drive shaft 25 is given one rotation, either by a manually operated crank or a motor, to complete the operation of the machine. Rotation of shaft 25 effects actuation of the cost totalizer by first returning all of differential segments 14, if left out of zero position on the preceding operation. Then cam 28 (Fig. 2) lifts the totalizer reel meshing the selected totalizer, and: following this movement differential segments 14, as controlled by the value keys, are rocked upwardly, thereby advancing the cost totalizer the required amount. Cam 28 finally lowers the reel to normal position. Before the registering movement of segments 14, the main totalizer is disconnected from intermediate gears 13 by arm (Fig. 9) engaging pin 126 in plate 127, thereby through link lifting pitman 114 out of engagement with pin 112 on the frame carrying broad pinions 107, and thus allowing spring 111 to unmesh pinions 107 with the totalizer pinions and intermediate pinions of the same size which receive movement from intermediate gears 13 (Fig. 6). The main totalizer thereby remains unaffected during the cost entry. The value indicators are set through their geared connection with differential segments 13 but are not exposed to view as screens 50 and 51 remain in concealing position. The screen returning mechanism consisting of pawl 59, arm 60, pitman 61, and cam 62 (Figs. 8 and 6), is made inoperative by the adjustment of lever 1 to the cost position, as at such time a pin 77 (Fig. 4) in 'ear 5 engages arm 76 rocking arm 74 to the position shown in Fig. 7. Arm 74 is then in the path of movement of pin 73 on pawl 59 and holds the pawl in an ineffective position when reciprocated. When a selling price is entered in the machine the lever 1 is adjusted to a position representing the class of transaction thus positioning pin 77 (Fig. 4) away from lever 76 and permitting the screen restoring mechanism to operate in its normal manner so that when pawl 59 (Figs. 7 and 8) is reciprocated it will engage pin 58, and return the screens to normal position, permitting the amount set in the indicators to be viewed. The adjustment of lever 1 may shift shaft 116 (Fig. 11) so that arm 125 is positioned below a pin in plate 127 or not depending on the class of transaction position of the lever. Accordingly the main totalizer throwout mechanism is effective or not as required by the class of transaction. As lever 1 is geared to disk 96 (Fig. 3) right with transaction indicator 6 and having a spiral groove for actuating segment 99, both transaction indicators 6 and 91 will be properly set. The screens 52 and 53 are operated through their connections with the screens 50 and 51 as shown in Figs. 5 and 8. The selected reel totalizer and the main totalizer are actuated through their gear connections with differential segments 14.

If desired the amounts of cost registrations may be. indicated to the operator while remaining hidden from the customer by removing the forward screen 51 and leaving the screen 50 in place providing the machine is suitably situated for this purpose.

' From the foregoing description it will be seen that the novel mechanism well adapts the machine to register cost and selling transactions, and that the construction is such that any desired totalizer may be used for cost registrations. Though the indicator shown is of the well known difi'eren may be used, the only requirement being that suchdevices be controlled by the indicating mechanism and be adjustable relative thereto, I M By the provision "of the twolindicators 6 and 91 and a driving connection between,

them, an indication may be gi'venof the par ticular totalizer employed together with" a full word indication of the class to which the transaction belongs. There, again, various types of indicating mechanism and connections may be employed, it being only necessary that the connections should cause movement of the indicating mechanismwhen some indicat ons of the otl' er ndlcatmg mechanism'are brought to exhibitlngtpo sition but prevent movement when others are brought to exhibiting position. The

, form shown, which provides a variable velocity ratio between the two mechanisms, is considered preferable.

While the form of mechanism herein shown and described is admirably adapted to fulfil the objects primarily stated, it is to be understood that it is not intended-to confine the invention to the one form of emacters on said indicator into position to be exhibited, a concealing means for said indicator, an operating mechanism for said concealing means, and means controlled by the indicator for preventing the operation of the concealing means when certain characters are brought into position to be exhibited, the said means being manually adjustable so as to prevent the exhibition of any desired character.

, 2. In a machine of the class described, the combination with a differentially movable indicator bearing a plurality of char acters, means for bringing any one of-the characters into position to be exhibited, a

concealing means for said indicator normally out of operative position, mechanism operated by the means for operating the indlcator, for controlling the movement of the concealing means to operative position, means for withdrawing said concealing means to an inoperative position and means controlled by the indicator for preventing the operation of the withdrawing means when certain characters are brought into position to be exhibited, the said means hemg manually adjustable so as to prevent the exhibition of any desired character.

3. In a machine of the class described, the combination with a differentially movable indicator bearing a plurality of characters any one of which may be brought into position to be exhibited, of concealin mear s for said indicator, means for with rawin ithe latter from concealing position, means comprising adjustable pins for controlling the operation of the withdrawing and means.

4.- In a machine of the class described, tl1e I combination with a differentially movabl e indicator bearing a pluralityof characters any one of; which may be brought into pos tion to be exhibited, of concealing means .fo r

said indicator, means including a pivoted f or. withdrawing the latter means from. concealing position, an arm for holdlng the latch in inoperative position when it is desired to retain the concealing means in operative position, and means comprising at.- justable pins for controlling said arm.

5. In a machine of the class described, the combination with a differentially movable indicator bearing a plurality of characters any one of which may be brought into posf tion to be exhibited, of concealing means for said indicator, means for withdrawing the tirlatter means from concealing position, mean s v for rendering the withdrawing means inop eMive, and an alining device for the indicator which is brought into operation only when the concealing means is withdrawn.

6. In a machine of the class described, the combination with a rotary indicator, anl means for differentially positioning it, of a screen for concealing said indicator, devices,

including a latch, for withdrawing said screen from concealing position, an arm for preventing or permitting movement of sail latch, and devices, comprising adjustable pins movable with said indicator, positioned to engage and operate said arm. j

7. In a machine of the class described, the combination with a rotary indicator and means for diiierentially positioning it, of a screen for concealing said indicator, devices, including a connecting latch, for withdrawing said screen from concealing position, and devices, comprising adjustable pins'movable with said indicator, positioned to permit or prevent movement of said latch.
